Usage Instructions

1. Select the appropriate type of silicon carbide tube according to the application scenario and parameter requirements;

2. Pay attention to the strength when installing and using, avoid violent impact, so as not to break or damage, reserve a certain space to ensure free expansion, avoid damage due to thermal expansion;

3.Do not contact objects containing too much water when used, and do not exceed the maximum use temperature, otherwise it may affect the life time of the silicon carbide tube;

4. When used for the first time or used again after long-term storage, it is necessary to control the heating speed and use low power heating to heat slowly;

5. The spare silicon carbon tube should be placed in a cool, dry and non-erosion place.
